refactor(cli): replace custom arg parsing with commander, expand test coverage

- Replace cli-utils monolithic index.ts with focused modules:
  io.ts (file I/O), service.ts (JSONL service), prefixes.ts (prefix parsing)
- Remove parseCliArgs / getFlag* helpers from cli-utils public API;
  these are now handled by commander in each engine's bin script
- Add injectable streams parameter to runJsonlService for testability
- Rewrite all three bin scripts (parser, generator, algebra) to use
  commander instead of manual argument parsing; commander provides
  built-in --help generation and cleaner option handling
- Fix bug in parser mergeContext: explicitly setting parseMode:undefined
  overwrites the parser's built-in default Set via spread, producing an
  empty parseMode Set and disabling variable/blank-node parsing for any
  request that carries a per-request context override
- Add comprehensive tests:
  - packages/cli-utils: service mode (valid requests, invalid JSON,
    handler errors, ID propagation, blank lines, non-Error throws)
  - packages/cli-utils: I/O utilities (file read/write, JSON parse)
  - All three engine CLIs: service mode round-trips, error responses,
    batched requests, missing-field validation
